This an idea originally based on a television show but I found that it worked really well with my students. Both teacher and student write down three experiences; the tricky part here, is that one of them is a lie. Then by "interviewing" each other, you try to find out which is the false experience. The more extraordinary the experiences the better. It is a very good chance get to know each other and have some fun whilst speaking English, like "Did you really do that!?!"

A slight variation is to have two experiences be untrue and then you have to guess the true one.
